Ok, sights back on these now. The Ferrari thing is just not looking like it's going to cut the mustard.

So my understanding is the Mezger engine is long gone -- 4.0 GT3 997 generation was its swansong.

Then we had the all new 3.8 in the 991.1 GT3 which it turns out had poor big end bolts so every engine was replaced under warranty.

Now I'm reading about a 500bhp 4.0 version with derivation from the present 991 GT3 cup car and it says dry sump lubrication.

How does this latest engine compare in motorsport terms to the fabled Mezger lump? Will history judge it to be a worthy successor?

Come on Anoraks -- now is your hour wink

Porsche state the best engine they have ever built, and it's the 1st GT3 in the new era of cars to have a race tested unit.
Looks like they have gone all out on it to me, sounds amazing when you read about it.

Maybe the 1st GT3 you can use on the road without it being annoying, Loads of grunt and that 9k limit, best of both.

Choose a manual and you have a better engine car for £120k than the 911R and even the 991 RS

Could be one of the best cars they have ever built.

Time will tell I guess.

Road tests are end of this month apparently so I am guessing we'll be hearing what the journalists have to say quite soon.

Sooo....

If one was to spec up a GT3 I don't see a huge number of options, PCCB would be one I'd choose, what setup would be closest to what you might consider a "clubsport"?

Also the massive question: PDK or Manual? For me I love stirring the old stick but frankly I've been won over by the fast and accurate PDK setups -- but would one ever be able to sell such a GT3 in the future (for me, prospect would be to own it at least 10 years like I did the GT2)

Leichtbauschalensitze (not sure re transaltion light weight buckets ...)
Manual transmission
PCCB
90L petrol tank
Clubsport
Cruise control

PDK in its basic format has aged very well......almost 9 years since it was introduced in the gen 2 Carrera.

Trouble is auto/manuel boxes clearly date quicker than true 'manuels' as the now hideous titptronic demonstrates.

The 991.1 GT3 PDK S box is still brilliant and better than the F1 Ferrari imo. Gen 2 PDK S will have even quicker change and shorter throw than the wonderful RS box.

And its 'free' too.

Either box on the gen 2 is the right one as both will suit the car and I am still undecided.

Well of course it would be better since Ferrari used a single clutch setup in the F1 gearboxes, you cant compare the two

Indeed, I was going to make the same point. And regarding tiptronic, that was outdated and completely unsuitable for a sports car IMO from the day it appeared (it's only a glorified slushbox -- and from a merc IIRC)

I think PDK holds the stigma of an auto and especially of tiptronic whereas it's a manual sequential box with unbelievably quick changes. I'd be really tempted to get one, although after all the fuss about getting Porsche to allow the option of a manual it seems like a bit of a waste.

For the record, I'd probably specify this, although I'd hope to have the courage to choose miami blue or lava orange instead of the "safe" grey.

I'd agree although OPC's may get a few more slots I suppose...certainly seemed with 991.1 RS there were a few extra slots allocated later in the production run. Hard to think each OPC doesn't have a long list ready to take the option though!

Everyone has their own story to tell when a GT3 is released....Your missing nothing.

No story here, mostly fantasy but just another dreamer with name on the list for the future gen 2 allocations.

Don't deflate my bubble lol.

All 2017 cars which will be the 1st 200, OPC will get 2018 cars also but they don't have numbers yet maybe another 200 plus.

So only the first 200 are allocated and none of those will be manual I think ! Well def not the first 100 odd as there is NO manual option yet and people have build slots already.

Yes I think most people will know if they have been allocated a car in the 1st batch, or on the reserve list for the next batch.

If you are on neither list by now, then you have got zero chance of getting a car.

In answer to the OP's question, the M engine was a development of the Le mans winning GT1 enigne, in simplistic terms basically without the turbos. So in that sense it was not puposefully built for GT3, just developed that way. It was a propper motorsport unit, propperly engineered, fully dry sumped etc.. with a very strong bottom end capable of withstanding 10,000 rpm or sometimes more and holding together. To date I believe it is the most successful GT racing engine that Porsche ever built. Like all racing engines, it was designed to safely handle sustanined high revs and consiquently the cam profiles, fueling and mapping were designed to capitalise on its revvy nature and consiquently peak power was achieved high up the rev range. For the drivers who actually understand this, it is a real peach of an engine. It is also extremely reliabe and relatively inexpensive to rebuild. In motorsport terms, it's been around for a LONG time (the 996 GT3 engine block had a 964 stamp on it for a while) but when judged by it's contemporaries its relatively thirsty, expensive to build and no longer competitve in GT racing - Hence the new engine.

On paper it looks a good unit, it carries more tech, is more efficient and has more development potential. It's already been round a development loop and now that it has found it's way into the cup car and GT motorsport catagories the development can really begin and - more importantly - we can all judge how good it is when compared by it's peers. Im sure that it will be a very good unit. Porsche rarely make a bad one at motorsport level.
